Products that do what Pie – an idiomatic C++ interface to CPython's C API does
I recently needed to add support for Python plugins in a C++ application I am developing. CPython's C API is pretty cool, but it's a C API. I wanted something more C++-ey, so I wrote Pie. https://github.com/ronmrdechai/Pie

I've been contemplating applying for HackerSchool, so I was looking at the application and saw the piece about FizzBuzz. I'd somehow never heard of this before. It is a trivial task in a conventional language, so I thought I would have some fun on a long internet-less train ride back to Rochester. "Piet is a programming language in which programs look like abstract paintings" http://www.dangermouse.net/esoteric/piet.html Doesn't it look kinda beautiful? http://benbrittain.com/imgs/fizzbuzzLarge.png here is a picture of the execution so you can see what is actually code.…

Google Docs for Python basically. For the past 4 months, I’ve been working on a full-stack project I’m really proud of called PyTogether; a real-time collaborative Python IDE designed with beginners in mind (think Google Docs, but for Python). It’s meant for pair programming, tutoring, or just learning Python together. It’s completely free. No subscriptions, no ads, nothing. Just create an account, make a group, and start a project. Has proper code-linting, live drawings for note-taking or teaching, voice chat, an extremely intuitive UI, autosaving, and live cursors. There are no limitations…

@cmpyl Tweet a line of python at it (right now it works best with math) and it'll tweet back at you the return value. Ex: https://twitter.com/#!/cmpyl/status/186850674053615616 Pretty useless little bot but it will be cool to see what sort of wild one liners it finds.

This is a little project I've been working on for a while in order to better learn Python. Although IRC may not exactly be the most exciting medium, I still find it to be fun and useful, this interest lead me to writing a bot. In doing this I realized that what would actually be more interesting would be if I had a framework. There may already be such a thing, certainly there are IRC libraries, but I don't know if they're well-suited to deploying bots. At any rate if for no other reason than the fact that I am relatively new to programming and eager to learn I decided to build a framework.…

Hi everyone. I've recently released control-components, a C++ library I've been using for most of my embedded projects. It is written in C++17 (with some features from C++20) and uses STL and FreeRTOS under the hood. It contains a lot of building blocks that is commonly used in embedded and IoT projects: finite state machines (FSM), various counters, synchronisation primitives, system loops, sensors, schedulers, HTTP, WiFi, Web GUI, and much more. It also provides GitHub CI workflows for build automation (ccache, various checks). In general, it's a good starting point for an ESP32 project.…

https://paste.woboq.org/ZuoGr5wfLV.cpp Have fun using, it should be able to link to all symbols that are present on https://code.woboq.org Technically it's a fork of haste-server that does Ajax calls to the code.woboq.org API.

As a beginner learning to build ML models, I found it annoying to have to keep printing tensor shapes every other line, having to step through the debugger to check where did I mess up the shapes again. So I built Trickle, it takes the data that flows through your code, caches the types and display them inline (as if you have type annotations). The idea is: "Let types trickle from runtime into your IDE". You get types in Python without having the write them manually. It works by rewriting your Python AST at import time — after every variable assignment, it inserts a lightweight call that…

Earlier this year, I took a month to reexamine my coding habits and rethink some past design choices. I hope to rewrite and improve my FOSS libraries this year, and I needed answers to a few questions first. Perhaps some of these questions will resonate with others in the community, too. - Are coroutines viable for high-performance work? - Should I use SIMD intrinsics for clarity or drop to assembly for easier library distribution? - Has hardware caught up with vectorized scatter/gather in AVX-512 & SVE? - How do secure enclaves & pointer tagging differ on Intel, Arm, & AMD? - What's…

I've been building a C++ tensor library that tries to bring the ergonomics of NumPy/PyTorch to native code. The main goals were: - Familiar API (operator overloading, method chaining, same function names) - Actual GPU acceleration via Metal (not just matmul, but all ops) - Cross-platform with SIMD on x86/ARM/RISC-V via xsimd - einops-style rearrange/reduce patterns It started because I wanted NumPy's API but needed to deploy on edge devices without Python. Ended up going deeper than expected (28k LOC+) into BLAS backends, memory views, and GPU kernels. Some things I'm…

I spent the past few weeks working on arguably. It uses your function signatures and docstrings to create a CLI. I built it to have the most common features of other libraries (and a few extra) in a much more concise syntax - no need for @click.option or typer.Option. It succeeds when you barely notice it's there. For most cases, you decorate a function with @arguably.command, and it just does what you'd expect: * Positional args for the function become positional CLI args * Keyword-only args become --options * Type hints set up parsing * Docstrings provide help messages for each command and…

Anyone like C++'s module features? Feel free to try MCPP and talk with me.

Hey HN! We built Achilles, a tool that automatically accelerates your Python code. It identifies performance bottlenecks, rewrites those functions in optimized C++, and seamlessly patches them into your running program—without you changing a single line of code. In CPU-intensive, loop-heavy tasks, we've observed performance improvements of 100-1000x. Achilles can be installed via pip and works with just a single command. We'd appreciate your feedback, and feel free to give us a star if you find it interesting!

Merry Christmas, everyone! Now you can compile Haskell code on Windows 11 ARM. It will run full speed if you use UTM/QEmu on Apple silicon. :-) It's a very draft version, but it works well. Any ideas?

Hi It's Logan (op) and David, we are launching our first open source Python SDK generator with other languages to come :) We built this because we believe that the OpenAPI Generator project is a mess and simply doesn't work for most users (us included). Additionally, proprietary generators miss the mark for complex use cases, and restrict developers from doing what they do best: writing code. On top of all that they force you into proprietary configuration layers for many desirable features which increases vendor lock in and pulls you further away from your API spec as the source of truth.…

Hi, We’ve built Pantheon-CLI, an fully open-source project that aims to be the “Python Claude Code + Notebook” — but designed for data analysis instead of just coding. Unlike most AI coding assistants, Pantheon-CLI runs entirely on your machine (or server). No data upload required. It blends natural language and code in a single workflow, keeping variables in memory and letting you switch seamlessly between typing code and asking in plain English. What it does: 1. Chat with your data: Directly process CSV, Excel, AnnData, Pickle, Torch tensors, or any format supported by…

I rewrote the most common core string.h functions in pure C. I mostly did it to learn pointers and string. Would love to get any feedbacks:)

This is a pretty straightforward port of Robert Smallshire's Python implementation to C. It type checks a factorial program correctly and is pretty fast. Mostly a learning exercise.
